The Arizona Department of Environmental Quality issued an Ozone High Pollution Advisory for the Phoenix metro area Thursday, warning that forecast weather conditions combined with existing ozone levels are expected to produce local maximum 8-hour ozone concentrations that pose a health risk. The advisory, relayed by the National Weather Service Phoenix at 8:49 a.m. MST, runs through 9 p.m. Thursday.
Ozone is an air contaminant that can cause breathing difficulties for children, older adults, and people with respiratory conditions. ADEQ states that adverse health effects increase as air quality deteriorates and recommends a decrease in physical activity for sensitive groups.
Residents are urged to carpool, telecommute, or use mass transit. Use of gasoline-powered equipment should be reduced or deferred until late in the day, when ozone-forming conditions are less intense.
